Stripe Response when Retrieving Customer Sources - php

Question

I am trying to retrieve all cards for a particular customer, by supplying a customer ID. Per the documentation, I am expecting the following response:
Stripe\Collection JSON: {
"object" => "list",
"url" => "/v1/customers/cu_16jdAj2eZvKYlo2CbrCP4HRs/sources",
"has_more" => false,
"data" => [
[0] => Stripe\Card JSON: {
"id": "card_14bIFkou9GUI42eZvKYlo2Cs",
"object": "card",
"last4": "4242",
"brand": "Visa",
"funding": "credit",
"exp_month": 11,
"exp_year": 2018,
"country": "US",
"name": "callingsudhanshu#gmail.com",
"address_line1": null,
"address_line2": null,
"address_city": null,
"address_state": null,
"address_zip": null,
"address_country": null,
"cvc_check": null,
"address_line1_check": null,
"address_zip_check": null,
"tokenization_method": null,
"dynamic_last4": null,
"metadata": {
},
"customer": "cus_6Nb0wxYHigk2mX"
}
[1] => <Stripe\Card[...] ...>
[2] => <Stripe\Card[...] ...>
]
}
And here's the request I'm making to Stripe. Trying to pull data (ie, an array of all cards) from the $card_list:
\Stripe\Stripe::setApiKey($this->stripe_sk);
$card_list = \Stripe\Customer::retrieve($customer_id)->sources->all(array(
'object' => 'card'
));
// Return a list of all cards.
$card_list = $card_list->data;
return $card_list;
I would like to know why the Stripe response from $card_list contains additional/unexpected data. Here's what I'm actually getting back:
array(1) {
[0]=>
object(Stripe\Card)#292 (5) {
["_opts":protected]=>
object(Stripe\Util\RequestOptions)#294 (2) {

}

["_elts":"Stripe\Util\Set":private]=>
array(0) {
}
}
["_retrieveOptions":protected]=>
array(0) {
}
}
}
Hoping that someone can explain the "extended" version of the response, that I'm getting here. Thanks in advance!

Answer 1

I stuck in this problem a couple of days ago and I've managed to solve it using json_encode() API like this (need to export this as a AJAX return on my side).
$cards = \Stripe\Customer::retrieve($_SESSION['stripe_customer_id'])->sources->all(array("object" => "card"));
$list = json_encode($cards->data);
echo($list);
Hope this helps.
BTW : Your response looks alike a var_dump() output.

If you want to normalize data in array form to get value easily then add __toArray(); to get response in array.
Ex: $cards->data->__toArray();
